Just running

/usr/lib/vino/vino-server should do the job.

Once you have access to your server, I would recommend that you add it to Autostarted Apps so it is always started.

You'll probably like change some settings with :

vino-preferences be very careful when you run vino-preference on a remote machine, if you uncheck "Allow other users to control your desktop", you won't be able to check it back.

or to edit :

~/.gconf/desktop/gnome/remote_access/%gconf.xml Here a sample file :

    misc vnc notes


    I would like to use VNC to access a Ubuntu 18.04 system from windows like I do with the Raspberry Pi.

    • Connect to the existing desktop
    • Keep the connection secure

    This has been a bit of a struggle for a number of gotchas.


    As I understand it ( may not have figured it out all the way )

    • VNC has a server ( run on the machine you wish to view ) and viewer ( run on the machine you wish to access).
    • In addition to having several components there are many versions of VNC. Directions for each differ, and differ across versions of Linux.
    • I will focus on Tiger VNC and Ubuntu 18.04
    • To get VNC working there seem to be various components.
      • VNC server
      • Desktop software ( there are many different ones, you may need to install -- however here I want to run on the default Ubuntu 18.04 desktop so no install is necessary )
      • A way to connect to the VNC server -- many servers will only connect to localhost so we will use vnc tunnelling to make a remote connection appear to be on localhost

    Other Software Used

    before installs

    • sudo apt update
    • sudo apt upgrade

    Process viewer (htop)

    • Why This will let you see what vnc software is running.
    • Install >> sudo apt -install htop
    • Run >> htop
    • Exit >> ctrl-c


    • Why see your server's tcp ip address
    • Install >> sudo apt -install ??
    • Run >> ifconfig
    • Exit >> just ends


    • Install >> sudo apt install openssh-server


    might this help gconf-editor

    Ubuntu text editor ( gedit )

    • Install >> apt-get -install ??
    • Run >> htop

    Ubuntu File Browser

    Tiger VNC

    • Note: there may already be vncserver software installed perhaps vineo ??
    • Install >> sudo apt-get install tigervnc-scraping-server
    • Install ( may not be needed ) >> sudo apt install tigervnc-standalone-server tigervnc-viewer
    • Set password >>vncpasswd << gotcha, if run server with no password set. If this does not run find an install -- perhaps full tiger vnc to get it.
    • Run gotcha >> x0tigervncserver << but gotcha, needs to be pointed to password file so
    • Run >> x0tigervncserver -PasswordFile ~/.vnc/passwd
    • Run gotcha this is not the scraping server may not be installed >> tigervncserver -xstartup /usr/bin/xterm
    • Set password >>vncpasswd << gotcha, if run server with no password set.
    • edit configuration file >> use file browser but .vnc is hidden so turn on hidden file abillity ( one of its menus )
    • set password with >> vncpasswd
    • see running servers >> vncserver -list
    • what runs with command vncserver >> which vncserver
        right answer is ??

    tiger vnc

    sudo apt install tigervnc-standalone-server tigervnc-viewer

    start in terminal with



    russ@UbuntuBase-VB:~$ vncserver

    New 'UbuntuBase-VB:1 (russ)' desktop at :1 on machine UbuntuBase-VB

    Starting applications specified in /etc/X11/Xvnc-session Log file is /home/russ/.vnc/UbuntuBase-VB:1.log

    Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/russ/.vnc/passwd :1 to connect to the VNC server.

    russ@UbuntuBase-VB:~$ vncserver

    loopback IP address is

    not done yet ------

    Start TigerVNC vncserver at boot

    The ubuntu install package also registers a system service, making it easy to define listening vnc servers on startup. Edit the file /etc/default/vncserver and add the display number and user to start as:

    sudo gedit /etc/default/vncserver


    Then enable the service at boot with:

    sudo update-rc.d vncserver defaults

    end not done

    vncserver in terminal to start

    Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/russ/.vnc/passwd :1 to connect to the VNC server.

    more installs --------------------


    sudo apt install openssh-server

    done ------------------


    sudo apt install software-properties-common apt-transport-https wget

    what is running tiger?? ----------------

    sudo apt-get install htop htop

    start with

    tigervncserver -xstartup /usr/bin/xterm

    remania connccts ok with password password

    590 desktop number may get the desktop number whhen start tigervnc with the command

    vncserver ??

    how do I know so little

    see what is going on with htop

       vncserver -kill :1

    vnc viewerr is also installed

    this seems pretty good

    ls ~ -a to see home hidden files there is a .vnc

    sudo gedit ~/.vnc/default.tigervnc

    How to list VNC server sessions on Ubuntu Linux $ vncserver -list

    sudo apt-get install openssh-server

    Input your password (no visual feedback while typing) when it prompts and hit Enter.


    3. Once installed, SSH starts automatically in background. And you can check its status via command:

    sudo systemctl status ssh.service
